Label columns not available for supervised learning in DL4J learner

Hello,

I have tried a workflow using DL4J that creates a simple MLP model.

But, I get an error that the Label column not available or not yet selected for supervised learning training. 

Is there anything wrong in the way I did that ?

Please find enclosed the screen shot for error. 

A bug ?

Thanks in advance for any help on that problem

Hi Kemal,

could you maybe attach a workflow reproducing the error? The same would be nice for your other question regarding the 'image_size'

Thanks.
